Planting and Management Technology of Honeysuckle

Honeysuckle has the effect of clearing away heat and detoxification. it can treat plague, fever, blood dysentery, wind-heat cold, throat pain, erysipelas and other diseases. it is widely used in traditional Chinese medicine prescriptions, the production and export of proprietary Chinese medicine.

Honeysuckle has strong drought resistance, barren tolerance and lax requirements for soil. It is suitable for mountains and beaches. It can also be planted in courtyards, forest banks, ridges and returning farmland to mountainous areas. It can be planted in both spring and autumn.

First, raising seedlings

Honeysuckle can be cultivated by seed, root division and cutting propagation, the propagation and growth of cutting seedlings is faster, it can blossom in autumn of that year, and the high yield period can be reached in the next year and the third year.

1. Strong branch selection: select one-year-old branches and vines that are robust, disease-free and flowering, and cut them into 15-20 cm nodes. Leave at least 3-5 buds in each node, cut off the lower leaves and make cuttings.

2. Land preparation: select a small field, apply basic fertilizer and refine it into a low or high border with a width of 1.2 meters. The row spacing of seedlings is 10-15 cm, the plant spacing is 5-8 cm, and 5000 seedlings are raised on 1-minute land for 8-9 mu of land.

3. Cutting time and methods: the best cutting time is from April to May, and two or three days after rain. Water in advance during drought to keep the soil moist. Drill the hole to insert the cuttings 3pm 4 into the ground, leaving 2-3 buds on the ground, compacting the gap. Watering immediately after cutting is beneficial to survival.

4. Management during seedling raising: cover plastic film or shade shed after cutting and preserve soil moisture. Sprinkle water every 3-5 days, but not too much. After one month, the shoots can grow well and get rid of the plastic film. The seedlings of the same year can grow to 1-2 meters high and have 2-3 branches for transplanting in the autumn or spring of the following year.

II. Planting and management

1. Fertilization and watering: honeysuckle had better be planted in a nest of 2-3 plants, 500-600 nests per mu, with a row spacing of 1.5 meters and a plant spacing of 1 meter. A litter of 2 kilograms of farm manure. Topdressing 2-3 times a year, overwintering fertilizer once, flower-picking fertilizer twice, soil fertilizer 1-2kg, watering and fertilizing at the same time during drought.

2. Scaffolding: honeysuckle is a semi-woody vine, which needs to be scaffolded to climb, which can increase flower yield. The frame is 1.2-1.5 meters high and should be strong and neat for use for many years.

3. Pruning time: from December in winter to February of the following year, the growing period is pruned immediately after flower picking. It should be cut again in winter and pruned immediately after flower picking during the growing period. It should be overhauled in winter and light in growing season. Cut off twisted branches, crossed branches, diseased branches, weak twigs and downward branches.

4. The method of pruning and shaping: in spring, honeysuckle first branched from axillary buds into primary branches, and then secondary branches, which could differentiate into four to six branches in a year. Axillary buds of new shoots redifferentiate into fertile branches, and inflorescences and flowers are formed on them. Cutting off the long vegetative branches before budding will quickly divide the secondary reproductive branches and increase the number of flower bud differentiation. Generally speaking, flower buds with first to fourth branches can form flower buds. The branches after the fourth grade can not develop into flower branches due to the decrease of temperature at the end of autumn. Pruning should be carried out early, and the top should be removed when it grows to 30-40 cm in the same year, forming a main rod, on which 3-5 vegetative branches will be produced. Spread out with three climbs or five fists as a first-class branch. The primary branches grow to 5-6 leaves and are still cut off when 15-20 cm long, promoting the growth of secondary branches. Remove weak branches and repeat branches in diseased branches to form third-or fourth-grade branches.

5. control of diseases and insect pests: the common disease is leaf spot, which can be controlled with 400 times Bordeaux solution or 100 times 100-fold clear water solution, once a week for three weeks. The insect pests are mainly aphids, which are killed by spray with 1-dimethoate aqueous solution.
